Abstract : The purpose of this effort was to develop a compact, lightweight, efficient S-band signal source for use with the project 'Balloon Boresighting Techniques,' DC 64-9. Theoretical studies were made with reference to the frequency neighborhood of operation, and to the stability of the tunnel diode oscillator-antenna, for the purpose of design. A study was also made to narrow and fix the neighborhood of operation. A test model 'Tunnel Diode Oscillator-Antenna' was constructed and tested. It was determined to have a frequency stability of about 1 part in 1000, put out approximately three milliwatts, have a power level stability better than one tenth of 1 db, and have a nearly omnidirectional antenna pattern.
